It is possible to enforce UK judgements and fines in the US, though my understanding is that it is not simple or guaranteed.
I suppose the action 4chan is taking in US court is exactly to avoid this possibility.

I am curious as to how that could possibly work. Is there some trade agreement that requires the US to respect UK court rulings? Generally the US has sought to distance itself from any kind of foreign influence or control.
